Quantum mechanics (QM; also known as quantum physics, quantum theory, the wave mechanical model, or matrix mechanics), including quantum field theory, is a fundamental theory in physics which describes nature at the smallest scales of energy levels of atoms and subatomic particles.

One of the central concepts in quantum physics is "wave-particle duality." As briefly as possible, here’s what it means. Any particle, such as an electron or proton, has a wave associated with it. This wave will typically extend over only a small region, and the particle will be somewhere in that region. Exactly where in that region the particle is, is unknown.
